Corn Sizer - Assuming the hybrid passes all of the required corn sizer tests, slow bucket elevators and conveyers now gently move the seed to the Sizer. This equipment separates the seed by width and thickness, so that bags will contain uniform sized corn seed. This is important to farmers because some planters require uniform size to maintain proper plant populations. To avoid hybrid mixing only from the corn sizer to allow even drying. Drying - seed corn must be dried slowly, at low temperatures critical step in maintaining seed quality. After the dried corn moves on, the dryer bins are kernel cleaned before receiving. Corn moves by conveyer to the designed to carefully remove the kernels from the cob, avoiding damage to the seed. Dried, corn. The seed is not dropped down into the bins; this would cause damage and result in poor seed quality. Spirals or seed ladders gently lower the seed. At this stage a number of tests are conducted such as warm germination tests to ensure the seed meets standards for genetic purity and quality. Slow bucket elevators and conveyers now gently move the Corn seed to the Sizer. This equipment separates the seed by width and thickness, so that bags will contain uniform sized seed. This is important to farmers because some planters require uniform size to maintain proper plant. After sizing, the seed sizer is nearly ready for bagging, but first it is treated to protect it from soil. At the same time, a dye is put on the seed to indicate that it has been treated.
